Abstract
Abstract A matchmaker facility (810) permits two processes that are to cooperate in a data interchange operation identify each other and to identify data formats they have in common. A facility (222) is provided for managing shared data "resources". Customized versions of resources can be created and co-exist with standard resources. A resource retrieval function determines whether a customized or a standard resource is to be returned in response to each request for a resource.
